Sometimes I want to have a video chat and a regular chat open at the same time, like if I am listening into a meeting and continuing a chat or monitoring a chat room for a response. Sometimes I also want to reference or search another chat room while I actually chat in another.
I have used the /popout chat command feature to help view more than one chat room at a time (or do anything else that requires the left panel or a larger screen in PureCloud and chat at the same time).
